TOBACCO PIPE.

Application filed March 28, 1921. Serial No. 456,397.

To all whom it may concern:

Be it known that I, VVILLEs W. ALLEN, a citizen of the United States,residing at Bakersfield, in the county of Kern and State of California,have invented certain new and useful Improvements in 2. Tobacco Pipe, ofwhich the following is a specification.

This invention relates-to new and useful improvements in tobacco pipes,and has for one of its objects to provide a device of this characterwhich may be readily cleansed and kept from becoming foul by thecollection of sediment in the stem or other parts and likewise providingfor the ready cleansing of the parts or the renewal of impaired orbroken parts.

With these and other objects in view the invention consists of suchnovel features of construction as herein described and shown and thenspecifically pointed out in the claims, and in the drawings illustrativeof the preferred embodiment of the invention;

Figure 1 is a longitudinal sectional elevation of the improved device.

Fig. 2 is a side elevation of the stem por tion of the device detached.

Fig. 3 is a side elevation of tapered lining members of the improvedpipe.

Fig. i is a view similar to Fig. 1, illustrating the manner of applyingthe improvement to a pipe having a curved tip or mouth piece.

The improved pipe comprises the usual bowl 10 and stem 11, the latterhaving a longitudinal relatively large bore 16, communieating with theinterior of the bowl centrally of its inner end.

Disposed within the bore of the stem is a tapered lining 12 with thelarger outer end flush with the outer end of the stem 11, as shown inFig. 1.

The stem portion of the improved pipe, represented as a whole at 13 isformed with a reduced terminal 14 provided with an annular shoulder 15.The reduced portion of the stem 13 is externally threaded, while thetapered lining 12 is internally threaded at its larger outer end so thatthe stem may be readily attached to and detached from the tapered liningwith the shoulder 15 bearing against the terminals of the stem andlining, as shown in Fig. 1. By this means the stem and mouth piece arejoined without any obstruction. or projection at their juncture as shownin Fig. 1.

The bore of the lining 12 being larger at the outer end is graduallyenlarged toward the mouth piece end, and the latter will be kept freefrom clogging as the draft in the pipe, when in use, will be toward thelarger end of the lining and thus carry sediment, if there be any,outwardlv without danger of its engaging the sides of the lining andbeing retarded thereby and choking the flow through stem and the mouthpiece. The lining member 12 will preferably be of a metal which will notcorrode by the action of the tobacco or the moisture therefrom. Theparts are easily detachable for cleansing or repair or the renewal ofimpaired or broken parts.

The bore of the stem 11 is uniform throughout except at the inner endwhere it is reduced to receive the reduced inner end of the lining 12,thus forming a relatively large space surrounding the lining for thegreater part of its length. A dead air space is thus formed between thelining and the body of the stem which serves as a non-conductor of heat.

The aperture in the bowl 10 with which the inner smaller end of thelining 12 communicates is located centrally of the tobacco receptacle,so that the suction is applied at the center of the mass of tobacco inthe bowl and thus insures a uniform and even burning. I

The preferred embodiment of the invention is disclosed in the drawingsand set forth in the specification, but it will be understood that anymodifications within the scope of the claims may be made in theconstruction without departing from the principle of the invention orsacrificing any of its advantages.

Having thus described the invention what is claimed as new is 1. In atobacco pipe, a bowl having a tubular stem internally tapered at theouter end and with a passage at the inner end communicating with thebowl and internally tapered, a mouth piece reduced at the inner end withthe reduced portion externally threaded, and a conductor member disposedwithin the tubular stem, the outer end of the conductor being internallythreaded to receive the externally threaded reduced portion of the mouthpiece and tapered externally at the outer end corresponding to andengaging the internal taper of the stem and externally tapered at theinner end cor responding to and closely engaging the tapered passagebetween the bowl and stem.

2. A tobacco pipe, comprising a bowl and stem with an internallytape-red seat at the outer end and an internally tapered passage betweenthe bowl and stem, a mouth piece reduced at the inner end. a conductorengaging over the reduced portion of the niouth piece and externallytapered to engage. the tapered outer seat of the stern and rigidlysupported between the stem and mouth piece. the inner end of theconductor being externally tapered to engage the tapered passage.

3. A tobacco pipe, comprising a bowl and stem with an internally taperedseat at the outer end, a mouth piece reduced at the inner end aconductor engaging over the reduced portion of the mouth piece andexternall; tapered to engage the tapered outer seat of the stern andrigidly supported between the stem and mouth piece.

In testimony whereof. I afiix my signature hereto.

VVILLES W. ALLEN.
